To (tZZ whom, it may concern.-

Be it known that I, VINCENT G. HAZARD, a citizen of the United States, residing at Wilmington, county of New Castle, and State of Delaware, have invented certain newand useful Improvementsin Winding-Machinesfiully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in machines for winding continuous lengths of materialsuch, for example, as paper-into rolls.

The improvements of the present invention have reference particularly to winding-machines of that class known as drum-winders, in which there are employed in the winding operation a winding mechanism and a laterally displaceable receiving core rotated thereby, to which the material is secured and upon which it is wound as itis thus rotated, the core and its roll of material in such machines being supported yieldingly in engagement with the winding mechanism and displaced laterally accordingly as the roll of materialenlarges and their displacement being resisted by the weight of the roll of material aided by resistance devices which force the roll of material against the winding mechanism. In such machines in order to secure uniform, compact, and smooth winding of the roll of material it is necessary that the resistance to lateral displacement of the roll of material should be maintained substantially uniform throughout the winding operation. As the roll of material enlarges, however, there is a corresponding increase in its weight and in resistance to such displacement, and in order to secure such uniform, compact, and smooth winding of the material this increase in weight of the roll of material must, as it occurs, be compensated for in some way.

It is the object of the present invention to accomplish this result; and to that end the invention consists, primarily, of means for offering to the roll of material as it enlarges a gradually-decreasing resistance during the first part of the winding operation and a gradually-increasing assistance during the latter part of the winding operation, such decreased resistance and increased assistance bein graduated according to the increase in weight of the roll of material. The means provided by the present invention for this purpose consists, preferably, of a weighted arm or arms projecting radially from a shaft which is rotated through suitable connections by the receiving-core as it and its roll of material are laterally displaced and which weighted arms when the shaft is so rotated move in the arc of a circle upwardly to a vertical or neutral position, thus offering gradually-decreasing resistance to rotation of the shaft and to lateral displacement of said receiving-core and its roll of material, and are then moved downwardly from vertical or neutral position, thus tending to rotate the shaft and offering a grad ually-i ncreasin g assistance to displacement of the receiving-core and its roll of material. This mechanism of itself constitutes part of the present invention when used as above described or when used, as it may be, simply for the purpose of offering a gradually-decreasing resistance or graduallyincreasing assistance to displacement of the receiving-core and its roll of material.

The present invention, broadly considered, is capable of application to machines for winding materials of different kinds; but as it has been designed with especial reference to machines for winding paper, and particularly paper as it leaves a paper-making machine, and as in such machines it has peculiar advantages it will for convenience be described in that connection.

In the accompanying drawings, Figure 1 is an end elevation of one form of paper-winding machine equipped with the present invention, part of the driving connections therefor being omitted. Fig. 2 is a side elevation of the same upon an enlarged scale and partly in section, and Fig. 3 is a section on theline 3 3 of Fig. 2.

Referring to said drawings, the frame of the machine consists of supports 1, provided with uprights 2 3. Mounted injournal-boxes 4 5 on the supports 1 is a pair of shafts 6 7, bearing winding rolls or drums 8 9, respec tively, preferably of equal diameter, said shafts being connected with a suitable source of power (not shown) in such Way as to be both driven in the same direction, as indicated by the arrows in Fig. 2, these rolls or drums being provided at their ends with inwardly-extending oblique peripheral recesses or grooves. Upon the shafts 6 7 are splined or otherwise suitably secured sliding clutch members 10, (only one being shown,) adapted to engage corresponding clutch members 11, (oneof which is shown,) borneby the winding rolls or drums, and when so engaged to operatively connect said rolls or drums with the shafts 6 7, respectively. The uprights 2 3 are provided with vertical guides 12 13, respectively, upon which are mounted sliding carriages 14 15, respectively, each of said carriages being provided with a bracket 16 at its lower end, forming a journal-bearing for the reception of a shaft 17, bearing the sleeve or shell 18, constituting the receiving-core to which the Web W of paper is secured and upon which it is wound into a roll, such core and its roll of material during the windingoperation resting upon and being rotated by the winding-rolls 8 9. The shaft 17 is squared at its ends in the usual way for the reception of a wrench, so that after the end of the Web of material is secured to the core 18 said shaft and core may be rotated by hand to Wind a portion of the web onthe core, and thus start the formation of the roll. The web W of pa- .per is led into the winding-machine from a paper-making machine and on its way to the core 18 passes over and under guide-rolls 19 20, respectively. The journal-bearing 16 in each of the sliding carriages 14 is split, so as to provide a hinged upper portion 21,which may be swung open Whenever it is desired to .insert or remove a shaft 17 and core 18, such upper member being provided with a latch 22, adapted to engage a projection23 on the sliding carriage, and thus lock said member in its closed position. The latch 22 is pivoted to the member 21 and is provided with a handle 24, by which it. may bereadily disengaged from the sliding carriage to permit said upper member being swung open.

Each of the sliding carriages 14 15 has connected to it a sprocket-chain 25, passing over a sprocket wheel 26 and under a sprocketwheel 27. The sprocket-wheels 26 are secured to a shaft 28, journaled in the upper ends of the uprights 2 3, while the sprocketwheels 27 arejournalednipon studs 29,secured in the lower ends of said upright-s, studs being employed at this point in order that there may be no interference'with the winding of the roll. Each of the sprocket-chains is preferably made in two sections connected by a turnbuckle 30, by which the length of the chainmay be adjusted, and also by a hook 31 on the end one section engaging, aloop on the end of the other section. Each sprocketchain is; yieldingly connected to its carriage by means of a lug 32. on the carriage, through which the shank: of the hook 31 passes, said shank being screw-threaded above the lug 32 to receive an adjustable-collar 33, between which and said lug is interposed a coiled spring 34.

It will be understood that as the winding tests rolls or drums 8 9 are rotated in the direction I of the arrows in Fig. 2 they will, by frictional engagement with the core 18 and the material previously wound thereon ,rotate said core and wind the web of material W thereon, said core and roll of material, as the latter increases in diameter, being laterally displaced relatively to the winding rolls ordrurns, and the sliding carriages 14 15, in which the core 18 is supported,moved upwardly thereby,and through the sprocket-chains 25 26 in turn rotating the shaft 28.

The mechanism thus far described of itself constitutes no part of the present invention. Neither is the present invention, broadly considered, to be limited to such mechanism or to machines of the type described. The present invention, however, has certain advantages in machines of this type,and will, therefore, in some claims be claimed'in combination therewith.

The preferred form of mechanism for securing uniformity in the resistance to lateral diplacement of the receiving-core and its roll of material will now be described. This mechanism consists of a weighted arm or arms 35, secured to and projecting radially, or substantially so,from the shaft 28, two such arms being preferably employed, located approximately in line with the ends of the roll of material being wound. The arms move with the shaft 28 in the arc of a circle, and during the first part of the winding operation resist rotation of said shaft, and consequently lateral displacement of the core 18, which they tend to force toward the winding rolls or drums 8 9, and during the latter part of the winding operation assist rotation of said shaft 28, and consequently lateral displacement of the core 18 and its roll of material. At starting the Weighted arms 35 oocupy substantially the position shown by full lines in Fig. 2, at which they exert their greatest resistance to or downward pressure upon the core 18 and its roll of material. As the Winding operation proceeds the arms 35 move toward a vertical or neutral position, and their resistance to or downward pressure upon the core 18 and its roll of material is thus gradually decreased in accordance with the increase in weight of the roll of material until the arms arrive at their vertical or neutral position, when such resistance or pressure substantially ceases. The winding operation being continued,.the arms 35, moving onward, gradually approach a horizontal position, and in so moving assist rotation of the shaft28, and thus instead of resisting lateral displacement of the core and its roll of Ina-- terial furnish gradually -increasing assistance thereto and relieve the winding rolls or drums 8 9 of the increase, as the same occurs, in the: weight of said roll of material.

Thearms 35 are preferably secured to collens 36, rigidly secured to shaft 28, and are preferably weighted by means of weights 37,

adjustable longitudinally of the arms, Where- IIO by, the resisting and assisting force of said arms maybe regulated to suit different kinds of paper or dilterent sizes of rolls.

In addition to the weighted arms the machine is preferably provided with a frictionbrake consisting of a strap 38, passing around a pulley 39, secured to shaft 28, one end thereof being secured to a fixed part of upright 2 and the other end to the weighted arm of a bell-crank lever pivoted in said upright, the other arm ll of which is adapted to be moved by hand out of and into engagement with a spring-catch 42 when it is desired to apply the brake to or release it from the shaft 28. The arm 40 is preferably weighted by means of a weight 43, adjustable longitudinally thereof, whereby the resistance of this brake mechanism to rotation of shaft 28 may be regulated. The shaft 28 is also provided with a gear'lt, engaged by a pinion 43, the shaft 4E6 of which is provided with a handwheel 47, by which it may be rotated when, after the completion of a winding operation, it is desired to return shaft 28, arms 35, and sliding carriages l-LL 15 to initial position. The shaft 46 is also provided with a ratchet 48, adapted to be engaged by a pawl 49 when it is desired to lock the pinion and shaft 28 against rotation by hand or to retain the sliding carriages in any desired position-as, for example, when introducing a new core 18 into the machine.
